Authorities said Beachum used a fake profile to post the threat on Facebook saying she was going shoot up the school.

It also mentioned several members of the school staff by name as well as "immigrants" living in suburban estates.

This is the threat a viewer shared with me that was posted on a Facebook page. Sheriff’s office tells Beachum used a fake profile to post. I asked if picture used in profile belonged to a student. I’m told that’s still under investigation. @wsoctvpic.twitter.com/P0Gc8FKC2y
